If it. is. necessaryto', raise the temperature, this is done-by admit-- ting steam throughcoil 23 while the agitators are'gently rotated-Q When the requiredtemperature has been attained, the agitators are operated at suitablespeed, and at the vsame time air of'suitable temperature, preferably,the same temperature as the milk or cream,- is injected from agitators18. The air facili- I .'.tates the separation of the butter fat fromation of churning. When the butter hasbeen thoroughly extracted from-themilk or' cream and is in 'suitable'granular form. it is suddenly chilledby injecting" cold air through the agitators, the butter thus formed andfixed in granular form is allowed the milk or cream and thus hastens theoper to flow out with the residual'milk into theadjac'ent worker 24. bylowerin the, forward end oflthe tank by means 0 erank. 9 and raisinggate 2 suddenly.

When thegranules have attained. sufficient firmness and while still suspended inthe water, the forward end of the tankis lowered, gate2 suddenlyopen'ed;andthe contents of the tank allowed to flow the usual'way.
